`To qllwhom it may concern:

Be it known that l, GEORGE FRASER, a citizen of the United States,residing at Toeka, in the county ol' Shawnee. and State ol' iansas, haveinvented certain new and useful Im roveinents inOil-BurningRevcrberatory maccs, oi' which the following is a specification. 'Y

My invention relates in general to i'urnaces, and more partitudarly tooil burning reverberatory furnaces.

The primary object of my invention is to provide :a reverberatoryfurnace in which crude oil or residuum may be successfully burned bvthoroughly mixing the sprayed. liquid fuel with an air blast in suitablequantities, reflecting and concentrating the generated heat to produceperfect. combustion, and discharging the gases in a state ol' pcrfectcombustion into a working chamber, thereby resulting in a. high,uniform, and evenly distributed heat, l'ree l'rom violent drafts,throughout the entire working cham-V ber.

A furtherobject. of my invention is to prof- Vide'an oil 'burnimrreverberatory l'urnacc,

which will be simptie in cimstructtm, inexpensive in manufacture, and`eliicient in use.

The embodiment oi my invent-ion hcrein disclosed niay oe generallydescribed as comprising an initial chamber, through o )cnings 1n thewall ot' which a plurality ol' mrners concentrioally extend,each'lairner comprismg inner and outer concentric tubes, an air Supplyconduit communicating with tho outer burner tubes, an oil su plyconduit.

iiurner tubes, a bridge wall intermediate oi the initial Chamber and aworking chamber, the top edge. of thc, bridge. wall being in the same,horizontal plane as the centers ot' the burners, openings leading intothe. initial clnnnlwr adjacent the bottom thereof through which air issu iplicd, valves for regulating theI supply of oil to the burners,gates controlling the supply of air both to burners and to the loweropenings, steam supply conduits communicating with the inner tubes ol'the burn ors, and' valves controlling thc supply of, steam to theburners.

Mv invention will be more' fully described hereinafter with rctcrencc tothe accompanying drawings, in which thc saine is illustrated as embodiedin aconvenicnt and practical form, and in which Figure lis a t'rontelevational view; Fig. 2, a central sectional view, showing one of the.burners on an enlarged scale; and Fier. 3, a vertical sectional viewonline, 3, 3, ig. 1., the surrounding wall being partially shown inelevation.

The sanie reference. characters are used to designate the salue parts inthe several figurcs ot' the drawings.

Reference letter A indicates the housing of flanges a, a on thc adjacentsections. Q

B designates the trout of the housing, which is also preferably made insections united by bolts extending through flanges vl). l) on thcadjacent sections, the front wall ol` thc housing being also united bybolt-s to the sidc walls A.

indicates the lire-brick liningof the ful'- nace, within which is formedan initial chamber lC and a. \\'orliing chamber l a bridge wall l) beingprovided intermediate of the said chambers. 'lhc initial cha mberEis-provided with au opening c leading thereto through which 'access may behad for the purpose of inspection. v l

j indicates one of the door vopenings leading to the working chamber forthe introduction and removalof.v the material after being heated. Y

Extending horizont-idly through the front wall ot' thc tire-brickIlining are openings, such as indica-ted at Eand l.}2,'through whichburners extend tothe interior of the initial chamber IC. Each ot theburners com rises an outer tube li' extending through tie corre.- sponiling opening, but spaced apart therefrom to form an anun ar passageway,and an inner tu be h located concentrioally within the outer tube( Anozzleor con-ical cap i is secured ,around the inner end of the outertube/H of' each burner, so as to torni a restricted annular passagewayleading to the interior of the initial chamber around the central tubeand a'ir supply conduit through which .air is forced at a suitablepress-nre, as, for instance, about eight ounces. An air conduit G is.provided with branches it and G extending through opcningsin the furnacefront to the interior o the initial chamber adjacent the bottom thereof.Gates g and g2 are rovided for controlling the passa e of air thoughsuch branched' conduits. he air su )ply conduitr y G is also'providcdwith upwardly diverging a. furnace, which is preferably made in sec!4tionsunited by bolts extending through 9; 'I esente branches'l-l, H2,which eoiiiiiiiiiiieate with the Outer-tubes U of the burners.
